Maybe the previous owner changed the air cleaner? Odd. . . My '14 Road King has THE 103 HO, and says so on the air cleaner.

Why would you do that? If you are going to the trouble to replace the cams there are much better choices than the Rushmore cams.

And we're right back to where we started.

I'm with the "only the wetheads are HO" camp. Hopefully someone can post a link to something factual

Note in the upper left this is a 2015 StreetGlide Special air cooled.

I don't know that there are "much better," only different... The HO cams are pretty darn good, and similar profiles were sold as Screamin' Eagle upgrade cams in the recent past.

Horses for courses. The HO cams do a splendid job as-is. As some here have attested, there is a marked difference between the "standard" profile 103 cams and the HO cams.

Perfect, good news is I'm convinced, bad news is you've got me thinking about that used 15 SG again

Because I was given a new take out set of HO cams from a 2015 and was just wondering how a stock 2010 103 would run if I dropped these in.

Compression ratio of the Twin Cooled HO 103 is 10:1. On the Air Cooled HO 103 it's 9.7:1. Maybe that's what some are thinking regarding the difference.
